Comparison of the mechanical properties of detachable balloons for embolotherapy.

PURPOSE

The forces of detachment and the durability of inflation of three different embolization balloons were compared: the Mini-balloon, the detachable silicone balloon, and the gold-valve balloon.

MATERIALS AND METHODS

Balloons were considered small (4-6 mm), medium (6-8 mm), or large (8-11 mm), depending on fully inflated diameters. Four Mini-balloons were used in each size category to compare detachment force and inflation duration against three detachable silicone balloons and three gold-valve balloons.

RESULTS

All small balloons detached with the same force, while the medium gold-valve balloon and large Mini-balloon detached with less force than their counterparts. The detachable silicone balloons had the shortest release times and a favorable detachment force profile. All balloons remained fully inflated for 11 weeks.

CONCLUSION

Most or all vessels should be adequately blocked with any of these devices.
